In papillary thyroid carcinoma, miR-874-3p suppressed tumour cell migration and invasion by downregulating the expression of FAM84A and served the same function in colon cancer, [39, 40] consistent with our findings that the miR-874-3p mimic inhibited EC cell metastasis and that the miR-874-3p inhibitor enhanced EC cell function. The gene discussed is LRATD1; the disease is colonic neoplasm.
